CHARLES MARLIN, OF NEW POINT, INDIANA.

MAP-HOLDER.

SPECIFICATION forming part of Letters Patent No. 279,961, dated June 26,1883.

Application filed March 29, 1883.

To all whom it may concern Be it known that I, CHARLES MARLIN, a citizenof the United States, residing at New Point, in the county of Decaturand State of Indiana, have invented certain new and useful Improvementsin Map-Holders; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

-My invention relates to a device for holding maps and charts and thelike; and the novelty consists in the construction and arrangement ofparts, as will be more fully hereinafter set forth, and specificallypointed out in the claims.

The maps or charts used in schools, educational apartments, offices, orthe like are ordinarily mounted with small screw-rings, and for servicewith this class of devices my invention isespecially adapted.

The device is fully illustrated in the accompanying drawings, which forma part of this specification, and in which- Figure 1 is a rear elevationof my invention, Fig. 2, a top plan view of. the sliding adjustablearms; and Fig. 3, a cross-section, showing the engaging-hooks in detail.

The device is cheap and simple in construction, efficient and useful inservice, and meets a want felt especially in school-rooms.

Referring to the drawings, in which similar letters of referenceindicate like parts in all the figures, A represents an ordinary tripod,having a vertical socket, B, with the interior of which connects athumb-screw, b. In this socket or sleeve B operates loosely the centerspindle, O, of a frame, 0, and this frame is vertically adjustable,being adapted to be locked in any desired position by the setscrewblocking the socket at the desired point. The frame 0 swings in eitherdirection on its pivot, and has secured upon its upper end guides c, inwhich operate horizontal sliding arms D. These arms-have tenons d, whichhave abearing against each other and slide loosely in the center guide,a, through which a thumb-screw, d, operates to lock the arms (No model.)

D when the proper adjustment'has been attained. Secured to each slidearm D is a hook, E, which, from its point of contact with the arm,extends downward, outward, upward, over the arm and downthe other side,inward, and then upward, terminating in a hook, 6, over which themap-rings are to be placed.

It will be observed that more than one map may be engaged upon the hooksat the same time, and that the hooks are adapted to allow the maps to bethrown from one side of the frame to the other, to exhibit both sideswithout disengaging. them from the hooks. The proper height having beenobtained by the vertically-adjustable socket B, the teacher ordemonstrator is enabled to readily turn the map so that it will squarelyface any part of the class, and may exhibit both sides of a series ofmaps or charts without disengagement or further adjustment.

Modifications in .details of construction may be made without departingfrom the principle or sacrificing the advantages of my-invention, theessential features of which will be readily understood from theforegoing description, taken in connection with the drawings referredto.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. In a device for holding and exhibiting maps or charts, a swingingadjustable frame having sliding adjustable arms, the said arms beingprovided with hooks E, secured to one side of the arms, and then extendoutward, upward, over the arms, thence downward and inward, terminatingin hooks e, substantially as and for the purpose set forth.

2. The combination,with the tripod A, vertically-adjustable socket B,and set-screw b, of the frame 0, having spindle O and guides c c, thesliding arms D, having tenons d, the hooks E e, and set-screw d, allconstructed and arranged to operate as and for the purposes set forth.

In testimony whereof I afiix my signature in' presence of two witnesses.

CHARLES MARLIN.
